Do you love the look of gallery walls but can’t work out how to perfect the layout other than hammering away and hoping for the best?
Just lay out the frames flat on the floor, starting with the largest item and working your way out, and tweak the arrangement until it’s pleasing to your eye. Then hang them one by one, remembering to hammer in each hook at the correct distance from the top of the frame.
If you’ve got a huge collection to arrange, you can take it one step further by cutting out pieces of butcher paper the size of each frame and arranging them with blu-tack until you’re happy with it. Then hang each piece, removing the corresponding paper before doing so.
